engine harness for $$$

it took me about 45 minutes to an hour to swap main harness in my 67. holley hp efi. i had to change a few connectors for non mopar parts on my car but this was included in that time frame. harness is like 500 bucks complete. i had 3 at one time and down to one on car and spare ive buchered that was my original harness. all cuz i wasnt finding solid trouble shooting leads to anything else.
